55 is the building closet to the trail. We often request the upper level of this building. It has a nice view of the canal and it’s an easy walk to Disney Springs.
I don’t remember the exact length but I think it’s about a mile and depending on your speed, it’s less than a 30 minute journey.
Just note, this building puts you a ways from the hospitality house. It is, however, next to a pool and only a block from the bus stop so we find it terrific.
